"'f WARPER OR SECTION BEAM HEAD.

YApplication led January 24, 1927. Serial No. 163,122.

My invention has reference to an improved warper or section beam head which may be applied tothe warper beams now in use,

which not only serves to maintain the yarn on the barrel but also operates to support the barrel in conjunction with the shaft or Agudgeon so as to offset the danger of knocking the parts out of true with oneanotlier Vduringr the course of the rough handling of the section beams.

A warper or section' beam is used on a warper machine to wind on an even sheet of yarn from spools, said sheet consisting of .varying numbers of` ends, ranging from 350 to 500 ends, and in length from 21,000 to 30.000 yards7 in preparation for the slasher or sizing machine which in turn is put on warp beams for the looms. In the usual construction these section or warper beams comprise a hollow barrel built up of wooden lagging with an iron shaft or gudgeon running through the center. said shaft being threadedon each end, with nuts and washers to fasten on the heads or iianges andare made from 8 to 1Q diameter and 54 long between heads. The heads or flanges are not rigidly secured to the barrel but are held in frictional contact to allow of relative movement.

It is very essential that these beams run true, otherwise they will strain the yarn and ycause excessive breaking of ends7 causing bad work and seconds in all following processes. It-has always been the practice to make these heads or flanges with a smooth face having holes in their centers to accommodate the shaft or `Qjudgeon to facilitate the turning or changing the position of the heads or flanges to balance the beam. It is customary in filling* these warper beams with yarn. to leave the yarn below the outer peripheries of the heads. iianges or when the beam is full. so that the beam can be rolled on the floor without damaging the yarn when moving the beams from one machine to another. In

' movingI these beams. a low two vwheel tilting truck is used and when unloading, the front end of the beam is rested on the floor and the other end is lifted or rolled from the truck by the section hand.` These beams when full of yarn weigh between 400 and 700 pounds each and when dropped too heavily on the floor the flanges or heads are knocked out of true with the barrel sometimes bending the shaft or gudgeon which is the only support for the beam head. The

force -of the impact is transmitted directly and solely to the shaft which under the weight of the yarn usually undergoes bendmotor breaking;` away of the internal supnor 'l It is an object ofmy invention to provide an improved beam head of simple but sturdy structure which effectively resists the untrueingy of the section beam which has application to the old forms of warper beams as well as to new ones.

Another object of my'invention is to provide a reinforcing beam head by adding a wooden disc or angle ring riveted or screwed on the inside face of the beam heads adapted to .tit snugly on the inside of the beam barrel., thereby to transfer the shockfrom the head or flange to the barrel of the beam which is in turn reinforced by the yarn wrapped therearound.

A further object of my invention is to provide a support for the end of the barrel when empty beams yare stacked upon top of ono another so that the.. ends of the lagging are not sheared olf as does happen with the 'from the detailed description which follows:

I attainvthese objects by the mechanism shown and illustrated in the drawing wherein: v f

Figure l is an elevational view of an end portion of a section beam, showing the improved beam head h aving a sheet metal inner face with an angle ring attached thereto. An improved inner support of laminated wood is also shown togeth er with the circular wedge screw for reinforcingr the same.

'Figure 2 is an elevational view of an end portion of a beam head showing a modified form of my improved beam head wherein the head is constructed of laminated wood and a wooden disc disposed on the inner face of the head. said head beingv used in conjunction with the conventional form of beam barrel.

Figure 3 is a vertical cross sectional view of the laminated wooden head shown'in Figure 2. i

Figures 4 and 5 are an outer face and vertical cross sectional views respectively of the improved beam head shown in Figure 1, the ksame being of an artillery wheel construction with a sheet metal covering` on its inner face, said sheetme-tal extending` over the rim of said wheel.

Figure 6 is a perspective view of the circular wedge screw shown and referred to in Figure 1.

Referring to Figure 1 of the drawings, 1 is my improved beam head with the angle ring 2, 3 the barrel, 6 the shaft or gudgeon, 4e the laminated internal support for the barrel and 5 the circular slotted wedge screw for clamping and holding shaft firmly in center of barrel and reinforcing the support 5, and 7 the end nut. In Figures 4land 5 this improved beam head is shown on a larger scale and more clearly.

Essentially the beam head is built up on the order of an artillery wheel having,` the spokes 8 meetingv in a common center and held together by the hub plate 9 on one side thereofrwhich will be called the cuter side. The other or inner side of the wheel is covered with a sheet metal facing; 10, the sheet metal extending over the ends of the yspokes to a point on the outer side just below the spoke ends whereby an annular continuous rim 11 is formed with a groove for a friction band or rope. On the inner face or side of the wheel thus formed is secured an angle ring 2 which is concentrically disposed with the wheel. This angle ring may be secured vby riveting'. welding; or in any other suitable way. The size of the angle ring is such as to fit snugly within the ends of the barrel 3. The angle ring is secured to the -whecl at its base or plane surface 12 and the barrel fits onto the cylindrical surface 13 of the angle ring.

The improved internal support 4L for the barrel is constructed of laminated Wood and has an 'opening in its central portion to receive'the shaft or gudgeon f. The number of these internal supports that may be used is arbitrary and may be left to the manufacturer. A common disadvantage with the prior art wooden internal support is that because of the fact that in ordinary construction (see Figure 2) the diameter of the central opening 19 of the support 2O is much larger than the diameter of the shaft, the

supports are centered on the shaft by being secured to an iron flange 21 at each end of 'the barrel. This securement is generally by screws 22 and the iron flange is held in position on the shaft by a set screw 28. In actual use, however, this construction has notfproved reliable for the reason that the jolts and impacts to which the barrel issubjected while in use cause the screws 22 to work loose and lose their holding grip. As a consequence the internal supports descend on the shaft since the opening 19 is much ylarger than the shaft, and the entire structure then becomes clumsy and cumbersome. Another evil with this old construction is that the set screw 23 often Works loose and rolls around inside the tends ofV the barrel wearing away a channel in the interior of the barrel by lthe continual rolling until the end of the barrel is broken off. I have found that by 'the 'use of a circular slotted 'wedge screw these evils may be avoided entirely. The screw shown in Figure 6 is 'a tapered cylinder having a smooth interior and a threaded exterior 14. A longitudinal' slot 15 is provided `to allow it Eto grip the shaft.' The screw is used by sliding it on the shaft and screwing' the end having the smaller diameter into the central opening Vin the internal support whereby an iron to iron contact is' obtained which `'is strong and preserves the original diameter of the shaft opening'. One of these screws may be used ness 4is important since any irregularitiesl such 'as filets will cause uneven strains 4von the yarn at the ends of the barrel or-wher` ever the filets are located. It will be appreciated that when. during the course of handling a beam, the 'beam is thrown `down,.the force of the weight of the yarn vvi-'llf'be distributed between lthe vangle ring of the head and the gudgeon, the major part falling `to the lot of the langle ring. In the 'beam head Y now in use this burden is borne "by the shaft alone -which Ioften land usually results in the bending; of the `shaft as well fas :discentering of the internal 4supports as Aabove stated.

The improved head `may ybe used 'with Vfa barrel having my improved linternal supports vor the usual construction shown in Fig. 2.

In Figure `2 is illustrated a modification of my beam 'head showing the same constructed from laminatedwood 17 and further showing vits use lin conjunction with the `usual ybeam barrel structure. As better shown in Figure 3 this wooden Wheel has vdisposed thereon on one vside thereof a concentric wooden disc 18 of a diametercom- Inensurate with the 'internal diameter ofthe `beam barrel to allow of a snug fit Within the ybarrel ends. In luse the effect and 'operation of this wooden form is the same as the embodiment above described. f

Although yI have mentioned the use on the beam head'of Yannular :supporting means stood that an annulaimeans ofa discon` tinuous nature will be serviceable although possibly not so w-ell. Studs, lugs, or bosses may be disposed on the inner face of the beam head in the path of a circle concentric with the beam head and so disposed as to t within and support the barrel ends.

The manner of use of my improved barrel end and its mode of operation are apparent by an inspection of the drawingsparticularly in view of the description above given and further remarks on these points are here consid-ered to be unnecessary.

A further feature of my improved beam head is that avhen associated with the barrel it provides through the medium of the angle ring or annular means, a support for the ends of the lagging. This becomes of importance in connection with the stacking and storage of unfilled beams when it is customary to stagger the beams one on the other, the beam head of one resting adjacent the beam head of the lower beam on the end of the barrel lagging which inthe usual construction is unsupported save for a slight frictional contact with the beam head. It is not infrequent that during the stacking of these beams these unsupported 4ends of the lagging are sheared off. In my improved construction this shearing cannot take place inasmuch asl the ends of the lagging rest solidly on the annular means provided on the inn-er face of my improved beam head.

All that has been Said above in the description of my preferred embodiment is offered by way of illustration and not limitation. I do not wish to be limited to the exact structure of the preferred embodiment shown and described, or to any particular material used inthe construction ofparts, or to the design of parts, but desire protection as against any variations in structure which utilize the prin- Vciple of my invention and fall within the purview of my invention and are within the spirit and scope of the following claim.

The invention having been set forth, what I claim as new and useful is as follows:

An improved warper'beam comprising in combination hea-d members, barrel member, internal supports for said barrel member, a gudgeon ypassing through said head and barrel members, said internal supports comprisingpdisc members of substantially the same diameter as the interior of said barrel member, said disc members being mounted on said gudgeon and disposed within Isaid Abarrel member, said head members having means thereon for projecting into and supporting the ends of said barrel member, and a longitudinally slit tapered c lindrical screw having a bore therein to s ide on said gudgeon and threads thereon for securement to each of said internal disc members.
